The utility model relates to the technical field of river channel desilting, in particular to a river channel desilting ship which is characterized in that a
deck is arranged on the outer wall of the top end of a ship body, a portable storage mechanism is arranged above the
deck, a desilting control mechanism is arranged on the side edge of the portable storage mechanism, a portable storage mechanism is arranged on the side edge of the desilting control mechanism, and the portable storage mechanism is arranged on the side edge of the desilting control mechanism. When the river channel dredging ship is used, through the arrangement of the mounting box, the submersible motor, the limiting shaft, the driving
bevel gear, the driven
bevel gear, a protective cover, a control shaft and a
cutting blade, the driving submersible motor is used for driving a mechanism to conduct transmission, and then the
cutting blade is driven to rotate; by means of the design, on one hand, the phenomenon that the
sludge blocks are too large to block the pipeline is avoided, on the other hand, it is further guaranteed that the
sludge removing work can be normally carried out, and the overall practical effect is good.
